US EV sales stay strong, but looming tariffs threaten affordability

July EV sales, up 6.6% year-over-year, were primarily driven by a 'buy now' urgency ahead of the federal $7,500 tax credit's September 30 expiry and looming tariffs. Automakers absorbed an unsustainable $12 billion in Q2 tariff costs, which could add $4,000-$6,400 to 2026 model prices, threatening future new EV demand. This dynamic is shifting interest to the used EV market, which saw a 33% inventory increase and 2% price dip, offering more affordable options that often qualify for a separate $4,000 credit also ending soon.

Analysis

The 6.6% year-over-year increase in July new-vehicle sales presents a misleadingly positive signal, as it is primarily driven by a temporary pull-forward of consumer demand. This urgency is fueled by the looming September 30 expiration of the $7,500 federal EV tax credit and the anticipation of significant price hikes from tariffs. The sustainability of new EV demand is questionable, with automakers having absorbed an estimated $12 billion in tariff costs in Q2 alone. The potential pass-through of these costs could increase average vehicle prices by $4,000 to $6,400, a substantial burden considering household incomes grew only 1% last year. While new EV inventory growth has slowed to just 9%, the used EV market is showing robust momentum. Used EV inventory has expanded by 33% year-over-year, coupled with a 2% price dip to an average of $36,000, creating a compelling value proposition for consumers. Notably, affordable used models like the Tesla Model 3 and Chevy Bolt EV are selling 20% faster than average, indicating a structural shift in demand toward the secondary market.

Key Decisions for Investors

• Investors should view the recent strength in new auto sales, particularly for EVs, with caution, as it likely represents a pull-forward of demand that could lead to a significant slowdown after Q3 2025.
• Consider automakers with strong positioning in the used vehicle market, such as Tesla and General Motors, as this segment is demonstrating resilient growth and faster sales velocity for affordable models.
• Closely monitor OEM pricing strategies for 2026 models, as the pass-through of tariff-related costs will be a critical catalyst determining future consumer demand and margin pressure across the sector.
